Hi.

Please copy/paste your complete server.xml configuration file (confidential 
things removed), so that we could have a useful look at it.
Please edit *only* the confidential things, not entire sections. Often, the 
issue is in the details.

A quick search on Google led me to this link:

Check the permissions on the directory.

tomcat code=exited status=203/EXEC

[Mary Wiegand]

I'm getting the following error when I try to run tomcat8.
tomcat code=exited status=203/EXEC

I've done a bunch of searching for things that might work but haven't had
any luck with anything and nothing seems to be straight forward.

I'm using ubuntu server 14.06 and tomcat8.

Any ideas would be awesome.

Thanks,

Re: Tcnative.dll apr-1.5.2-win32-src - unable to compile with openssl-1.0.2j-fips-x86_64

Hi Mark,


I was able to work through the cmsc failed error.  I rebuilt my environment 
with Visual Studio 2010 and this resolved the issue.


I'm experiencing another issue below, when I'm compiling the openssl source.


   error LNK2005: getenv already defined in MSVCRT.lib


and

I've never seen that error. Is VSBaseDir set correctly?

Class loader resources have special handling. I think you'll be able to
get this to work with:

standardRoot.createWebResourceSet(CLASSES_JAR, "/WEB-INF/classes",
new File("target/classes").getAbsolutePath(), null, "/");

If that doesn't work, I'd recommend using a debugger to figure out what
is going on. It wouldn't surprise me to find we need to extend the API
as more use cases emerge.

Tomcat will be picking them up from the class path. You can enable trace
level logging for StandardJarScanner to get more detail on what is going on.

I am trying to launch a Tomcat instance by assembling the WAR from different 
places. The addPre/PostResources seem to allow that.




Ultimately, you will not be able to deploy a web application unless it
is properly-assembled into a WAR-like structure. You can't get around
that, embedded or not.


In my search I found many examples of starting tomcat without building a full 
WAR structure:
http://stackoverflow.com/questions/23143697/adding-external-resources-to-class-path-in-tomcat-8

The main problem is that the WAR project, as created in Eclipse by the Maven 
plugin, writes the class files to target/classes instead of 
webapps/WEB-INF/classes.

Re: Upgrade fom Tomat 8.0.33 to 8.5.9 - stuck clients

[Enrico Olivelli]

After rolling back to old Nio all clients works very well as expected.


I'm sorry, I don't know how to reproduce this kind of issue on a test case,
I have tried to write some simple multi-thread tests but I cannot break
Tomcat Nio2 connector, it happens only on my QA environment.

At this point I'm not able to submit any issue to your bug tracker.

What is weird is that it is looking for the commons-io artifact in a
totally wrong repo group. The project was setup by Eclipse's Maven plugin
(import maven project), and commons-io is indeed part of the project's
Maven dependencies, but in the correct location. The correct commons-io is
also scanned, but somehow 30ish of those incorrect permutations of group
and artifact id are also scanned.

Now these are warnings, so no fuss, but still strange?

Multiple directories under /WEB-INF/classes

[Tom Eugelink]

I'm trying to migrate a very old ANT based project into the future, the
ANT scripts I inherited are (of course) very complex, so I need to make
babysteps. The first thing I did was compile the Java code with Maven and
thus replaced a lot of copy statements and checked in lib directories with
dependencies. This is working fine, but it also means that there is no
single directory anymore where all the classfiles, jars, configuration
files, etc are copied to. So now I need a way to start Tomcat for
developers using (still) separated directories.

The best approach seemed like to start Tomcat embedded, this also allows
me to use it for running cucumber and integration tests against. The thing
is I cannot get it to work, even after searching google, stackoverflow and
reading the Tomcat (8.0.39) configuration guides for 2 days. It should, I
would not mind if it did, but it does not.

To begin I have a maven project with:
- classes in target/classes
- web files in webapps
- configuration files in /somewhere/outside/the/project/cfg

This what I have so far:
StandardContext standardContext =
(StandardContext)tomcat.addWebapp("/myapp,
"/path/to/maven/project/webapps);
standardContext.setCrossContext(true);
standardContext.addParameter("SomeOwnFramework.Home",
"/somewhere/outside/the/project");
standardContext.addParameter("SomeOwnFramework.ContainerName",
"MijnCaress Backend Container");

standardContext.addParameter("SomeOwnFramework.XmlConfigurationFile",
"/somewhere/outside/the/project/cfg/Framework-backend.xml");

standardContext.getNamingResources().addResource(createJdbcResource());
// returns a
org.apache.tomcat.util.descriptor.web.ContextResource

org.apache.catalina.webresources.StandardRoot standardRoot = new
org.apache.catalina.webresources.StandardRoot(standardContext);
standardRoot.setCachingAllowed(true);
standardRoot.setCacheMaxSize(10);
// add classes
standardRoot.addPreResources(new
org.apache.catalina.webresources.DirResourceSet(standardRoot,
"/WEB-INF/classes", new File("target/classes").getAbsolutePath(),
"/"));
// add configuration files
standardRoot.addPostResources(new
org.apache.catalina.webresources.DirResourceSet(standardRoot,
"/WEB-INF/classes", new
File("/somewhere/outside/the/project/cfg").getAbsolutePath(),
"/"));
standardContext.setResources(standardRoot);

This ends with a ClassNotFoundException on a class that is in
target/classes, also if I remove the configuration files resource.
The target/classes absolute path is correct, exists and contains the class.

It would be great to get some pointers on why this is not working.

Tom

Web sockets - issue with proxy handling

[Svetlin Zarev]

Hi all!

Recently I stumbled in a possible bug in WsWebSocketContainer. When
connecting to server, if the authority in the URI does not contain the
remote port, the proxy rejects the connection. In WsWebSocketContainer the
port is determined based on WS/WSS when constructing the InetSocketAddress
for non-proxied communication. But when using proxy, the WS/WSS scheme is
ignored and the CONNECT request looks like:

CONNECT gmail.com HTTP/1.1

So the proxy does not know to which port to open a tunnel. And as a result
connectToServer() fails with DeploymentException due to the proxy rejecting
the connect request.

Patch proposed: https://github.com/apache/tomcat/pull/39
What do you think ?

Best regards,
Svetlin

Hi,



We have installed Apache Tomcat/8.0.14, and found that after one period of 
time, the thread count for 8080(our port published) goes to 120 and never 
reduced even the busy count is only 3-4.

Why? Tomcat8 not reduced the thread pool even the thread is idle, and the 
minSpareThreads for tomcat8 default is only 10.

When will the thread reduce?





Best regards

Smith




Hi.

Please copy/paste your complete server.xml configuration file (confidential things 
removed), so that we could have a useful look at it.
Please edit *only* the confidential things, not entire sections. Often, the issue is in 
the details.

Yes, the NPE happens in application code so you have to ask developers of 
that app.
